HOUSTON — The son of TNT basketball broadcaster Craig Sager says his father is set to undergo a third bone marrow and stem cell transplant Wednesday as he continues his cancer fight.

Craig Sager II announced the procedure on Twitter on Tuesday, saying the marrow will be provided by an anonymous donor. NBC announced last month that the 65-year-old Sager was preparing for the transplant at MD Anderson Cancer Center in Houston and couldn’t take part in Olympics coverage. Sager was first diagnosed with leukemia in 2014 and announced in March that he was no longer in remission.

Sager II also thanked his father’s TNT colleague Charles Barkley on Twitter for keeping his dad company in Houston.

Sager is known for his outlandish suits and strong rapport with NBA players and coaches.
